For this tutorial you will need:
= A few sheets of cardboard
= PVA Glue
= Kitchen Roll or Tissue
= Yellow Paint
= Varnish (preferably matt depending on how you want your end product to look)
= Craft Knife
= Paint Brush or Sponge
= Darker Yellow Paint
= Cotton Buds
= Super Glue
Step 1: Cutting the Template
I used the one on this link
You don't have to do this but it helps. Print the image off as big as you want it then you can stick it to the first sheet of paper as a guideline for where to cut out with the craft knife.
After cutting out the first one you can use that as the template for cutting out the shape again on the other cardboard. The number of layers is up to you, I used 3 sheets but you might want it thicker or thinner depending on how thick the cardboard is. Stick them together
Step 2: Making It 3D
Then glue the string over the sections that are meant to be the highest, the swirly bits can be a bit fiddly. I used super glue to stick the string down but I imagine that PVA glue would work fine, it would just take longer to dry. (I forgot to photograph that bit)
Then Paper Mache the whole thing, do as many layers as you think it needs. I did about 2 and a half layers, make sure you don't loose the shape and the grooves of the frame.
Step 3: Painting It
Paint the whole thing yellow.
Step 4: Varnish It
Find your own way to stick it onto your door. Because it's only cardboard and paper mache it isn't very heavy so you could glue it on. Another way you could attach it is to put a pin or a nail in you door so it sticks out a little bit and make a hole in the back of the frame and hook it on.
I hope this tutorial has been helpful :)
